Hi Prakash,
implementing the a JSch logger gives you more information on the start up
(connect and key exchange) of a connection.
To cope with your timeout-problem, try setting the session's timeout before
connecting using "session.setTimeout(int timeoutInMilliseconds)".
And upgrading to a more recent version of JSch might be a good idea. :)
Greetings
Volker

Betreff: [JSch-users] jsch session connect waits indefinitely
Hi,
I am using JSCH 0.1.44 and trying to execute a remote command on a Solaris Host
and the
session.connect() waits indefinitely.
JSch jsch = new JSch();
Session session = jsch.getSession(m_user, m_host, m_port);
session.connect(60000)
Jstack thread dump shows the following stack trace
java.lang.Thread.State: RUNNABLE

What could be the possible causes for this connect issue.
Any debug statements I can add to triage this issue ?
thanks,
Prakash
